摘要：

A neutron diffraction study of ZrMn2D3 at room temperature shows that the deuterium atoms occupy tetrahedral interstices which are formed by two Zr and two Mn atoms. The interstices are partially occupied and represent a 3-dimensional infinite network of diffusion paths for the D atoms. Each D atom site in this network is about 1.3 Å away from at least two other D atom sites. It is suggested that the positional disorder of the D atoms is thermally induced. © 1979.
